As shown in FIG. 1, the control server 100 of the present invention includes a communication unit 110, a processor 120, and a database 130, and in some cases, a database 130 unlike FIG. 1 I can't. In this case, the processor 120 of the control server 100 may communicate with the database 130 through the communication unit 110.

First, the communication unit 110 of the control server 100 may be implemented with various communication technologies. That is, Wi-Fi, Wideband CDMA (WCDMA), High Speed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), High Speed Packet Access (HSPA), Mobile WiMAX, WiBro , Long Term Evolution (LTE), Bluetooth, infrared data association (IrDA), Near Field Communication (NFC), Zigbee, WLAN technology, etc. may be applied. In addition, when a service is provided by being connected to the Internet, TCP/IP, which is a standard protocol for information transmission on the Internet, may be followed, or a Global Positioning System (GPS) technology may be used.

Next, as will be described later, the database 130 of the present invention may store operation information of stores and the like, and the processor 120 may access the database 130 through the communication unit 110. The processor 120 will be described in detail later through detailed description.

On the other hand, the processor 120 of the control server 100 of the present invention may communicate with the user's portable terminal and the operator's portable terminal through the communication unit 110. For convenience of explanation, the user's portable terminal will be referred to as the first device 200 below, and the operator's portable terminal will be referred to as the second device 300.

For reference, the user's portable terminal or the operator's portable terminal is a digital device that includes a function to perform communication, and has a memory means such as a mobile phone or a tablet PC, and is equipped with a microprocessor to have computing power. Any digital device for portable purposes can be adopted as the devices 200 and 300 according to the present invention. In particular, the first device 200 and the second device 300 may include a payment program (application) using a QR code dealt with in the present invention.

2 is a diagram sequentially illustrating a process of scanning and updating a QR code usage right according to an embodiment of the present invention.

3 is a diagram showing a state in which store operation information is stored in a database according to an embodiment of the present invention.

As can be seen in FIG. 3, operation information of a plurality of stores including a first store and a second store may be stored in the database 130 of the control server 100. For reference, the plurality of stores will correspond to stores affiliated with a company that operates the control server 100 of the present invention.

In addition, the operation information may include at least one or more of the type, price, and quantity of food sold by each store. Specifically, as shown in FIG. 3, the operation information of the first store includes information corresponding to Korean food (ex bibimbap, bulgogi, etc.), price range of 10,000 won or less, and daily sales volume of 100 servings or less, and operation information of the second store The row may include information on Western food (eg steak, pasta, etc.), price points of 30,000 won or more, and daily sales of less than 50 servings.

Of course, unlike FIG. 3, the operation information may include various information necessary for the operation of the store, such as rating (recommended) information, review information, number of customers, location information, and quarterly sales volume for each store. In addition, it is also possible to include in the database 130 as operating information, price, daily sales, etc. for each menu (ex bibimbap, bulgogi, steak, pasta, etc.), not the store itself.

In relation to the information stored in the database 130, the processor 120 of the present invention shares the information of the first store with a first external company that conducts a business corresponding to the operation information of the first store, and It is also possible to share the information of the second store with a second external company that conducts a business corresponding to the operation information of. This may correspond to a structure for profit of a company conducting business according to the present invention.

Specifically, suppose there is a company called A that sells high-priced ingredients such as high-end beef, high-end fruits, and high-end vegetables, and a company called B that sells low-priced ingredients such as low-end beef, mid-range fruits, and low-end vegetables. I'll see.

As can be seen in FIG. 3, in the case of the first store, foods with a price of less than 10,000 won are sold, so in terms of ingredients, low-priced ingredients will be inevitably used. Accordingly, information on the first store may be provided to Company B. Conversely, information on the second store, which sells foods over 30,000 won, can be provided to Company A. In other words, it is possible to conduct business by providing the information obtained according to the process of the present invention to a company in need.

4 is a diagram illustrating a process in which a process according to an embodiment of the present invention is displayed on a user's terminal.

The processor 120 of the control server 100 may display a first store and a second store included in a predetermined category among a plurality of stores stored in the database 130 on the screen of the first device 200 (S210). have.

It can be displayed in a map format as shown in FIG. 4(a), or in a list format as shown in FIG. 4(b).

The predetermined category may vary according to setting information. Here, the setting information includes information on the distance between the user and the store, information on the price of food sold in the store, information on the food menu in the store, information on the store's evaluation (review, recommendation, rating), information on the opening time of the store, and the rest of the store. Information, etc. may be included. That is, the predetermined category may be set based on at least one or more of a plurality of setting information.

For example, the processor 120 may designate food price information (about 10,000 won) and store evaluation information (recommended number of 50 or more) as setting information, and set a predetermined category based on this. In this case, only stores that provide foods worth 10,000 won and foods with a recommended number of 50 or more may be displayed on the screen of the first device 200.

Depending on the situation, the processor 120 may designate food price information (10,000 won) as primary setting information and store evaluation information as secondary setting information, and set a predetermined category based on this. In this case, only a food menu of 10,000 won is provided, and the stores that sell the food of 10,000 won are listed in the highest order of evaluation and displayed on the screen of the first device 200. That is, only store information corresponding to the primary setting information is filtered, but an order is determined based on the secondary setting information, and a list thereof is provided.

The setting information may be designated by the processor 120 of the present invention, or the user may directly designate the setting information as shown in FIG. 4(c). Priority of setting information (primary setting information, secondary setting information) may also be designated by the user.

Depending on the situation, a list may be provided accordingly by prioritizing when a predetermined amount is paid from among stores. In this case, a store that has paid a predetermined amount may be displayed separately from a store that has not paid the predetermined amount.

On the other hand, the processor 120 of the present invention may use information on the leftovers of each store, that is, whether or not there are leftovers.

For example, when a first store and a second store are included in a first predetermined category based on residual information, the processor 120 of the control server 100 displays the residual value of the first store on the screen of the first device 200. The first bento product information using and and second bento product information using the leftover of the second store may be displayed.

Specifically, if the user or the processor 120 specifies whether or not the residual is present as the setting information, stores where the residual is present will be displayed on the screen of the first device 200. In addition, in the case of a store in which a residual table exists, information on a lunch box product that can be made based on the residual table may be provided to users. Depending on the situation, other setting information, such as evaluation score for lunchbox products and distance to the store, can be designated as secondary setting information, and based on this, the priority for the store in which the leftover exists can be determined, ordered, and displayed. There will be.

This is because not only food stores but also domestic buffets, catering establishments, cafeteria, student cafeterias, and dormitory restaurants, etc., it is best to ensure that most of the food prepared within a set business day is consumed.

Of course, a plurality of users may exist, and the plurality of users may include a first user with a high rating and a second user with a low rating according to their grade. The rating may be determined according to various methods, such as a period of using the application of the present invention, an amount of payment, and the number of times a review is written.

The processor 120 gives a first user an opportunity to set a predetermined category by combining a predetermined number or more of setting information among a plurality of setting information, and a second user is given a predetermined combination of setting information less than a predetermined number of the plurality of setting information. Lets you set categories.

For example, a first user with a high rating can set a predetermined category by combining two or more setting information among a plurality of setting information, but a second user with a low level can set a predetermined category using only one setting information. There is.

Specifically, the first user may receive information on stores corresponding to both evaluation information (ex. 4 or more of 5 stars) and price information (ex 20,000 won or less), but the second user may receive evaluation information or price information. It is possible to receive information on stores corresponding to any one of them.

In addition, the processor 120 gives the first user an opportunity to set a predetermined category using specific information from among a plurality of setting information, and gives the second user an opportunity to set a predetermined category using information other than the specific information among the plurality of setting information. You can let them set categories.

For example, it can be assumed that the specific information described above is the residual information of the store. In this case, the processor 120 displays on which store the leftover is left and whether the lunch box is provided on the portable terminal of the first user, but the second user's portable terminal displays whether the leftover is left in which store or whether the lunch box is provided. Whether or not is not displayed. After all, it can naturally induce users to try to get a high rating.

The processor 120 of the control server 100 assists the user to select at least one specific store among stores displayed on the screen of the first device and purchase a specific QR code usage ticket corresponding to the specific store (S220) can do.

The specific store may correspond to various stores such as Western restaurant, Chinese restaurant, and Japanese restaurant, and QR code usage rights for each store may be different. The method of purchasing the specific QR code usage voucher may be various, such as card payment and account transfer.

In addition, the processor 120 may support a user to purchase a specific QR code usage ticket corresponding to a specific store and present it to another person. In this case, whether to use a specific QR code usage right may be transmitted to the first device 200.

Therefore, a meal manager of a large company can purchase a QR code ticket as a group and present a QR code ticket to the employees of the company, and check whether the QR code ticket has been used to conveniently manage employee meals. I can.

5 is a view showing a state in which QR code usage rights are managed in a user's terminal according to an embodiment of the present invention.

As can be seen in FIG. 5, when a user purchases a QR code usage ticket, a corresponding store name, validity period of the usage ticket, and QR code may be displayed and managed on the first device 200.

When a user purchases the above QR code voucher, the solar eclipse method purchased individually (ex 1, 5, 10, etc.) or the lunar eclipse method purchased in a period of 1 month (but not 1 month, but 1 week, 1 year) Etc. The period may vary depending on the setting).

At this time, for convenience of explanation, it is assumed below that if the QR code use ticket is purchased in a solar eclipse, it is a first QR code use ticket, and when it is purchased in a lunar eclipse, it is assumed as a second QR code use ticket.

The processor 120 categorizes, respectively, i) store information of the first QR code voucher, validity period, QR code, ii) store information, expiration date, and QR code of the second QR code voucher on the screen of the first device 200 Can be displayed. For example, as shown in FIG. 5, tabs may be divided and displayed, or different windows may be divided and displayed.

Meanwhile, when a plurality of stores are displayed on the screen of the first device 200 based on the predetermined category, information on the stores may also be displayed.

For example, store name, rating information, review information, price information, distance information, and the like may be displayed together. This applies to both map and list formats.

In addition, whether the user has previously purchased a QR code voucher for the store, how many QR code vouchers remain if purchased, and the number of earned stamps generated according to the purchase of a QR code voucher are displayed together. It could be.

When the specific QR code usage right is scanned, the processor 120 of the control server 100 may update operation information for a specific store included in the database 130 (S230). That is, when a specific QR code usage right is scanned, it is deemed that the user's purchase intention to use a specific store is confirmed, payment is made to a specific store, and information about this is updated in the database 130.

Specifically, when a specific QR code use ticket is scanned, the daily sales volume of food sold in a specific store stored in the database 130 will be updated, and the first device 200 and the second device 300 will have a specific QR code use ticket. A notification will be provided indicating that is used, ie the transaction has been completed.

Of course, payment is not made by scanning a specific QR code usage right, and after the scan, the processor 120 can send a push message asking whether or not to agree to the payment, and the user first Payment may be made upon approval through the device 200.

The act of scanning a specific QR code displayed on the screen of the first device 200 using the camera of the second device 300 described above will generally be performed by a specific business operator who is the owner of a specific store.

However, in the present invention, even if there is no owner in the store, a method of using the store by directly scanning the QR code is considered by the user, and this will be described below.

First, a specific operator may leave the second device 300 alone at the entrance of the store and wear a wearable device (eg, a smart watch) while working in a kitchen or the like. In this case, the wearable device may be assumed to be a third device (not shown) for convenience of description.

The processor 120 of the control server 100 directs the user entering the store to scan a specific QR code usage ticket displayed on the screen of the first device 200 through a camera included in the specific second device 300. can do. In other words, the user does not scan one by one by a specific operator, but allows the user to scan.

Thereafter, the processor 120 reports that the transaction has been completed and updates the operation information (ex, daily sales volume, etc.) included in the database 130, and transmits the updated operation information to a third device (not shown) or a second device. It can support 300 to transmit.

A specific business operator located in the kitchen will be curious about whether the user who entered the store has paid or not, and the processor 120 of the control server 100 transmits information on the payment status to a third device (not shown) worn by a specific business operator. will be.

Of course, depending on the situation, the processor 120 may command the second device 300 to transmit the payment without directly transmitting the payment status to the third device (not shown).
